You can tell the film was originally envisioned as a comedy...
Like Dr Strangelove.
Heck the wikipedia article even says Steve Martin was Kubrick's idea for the lead at that point.
It's so full of BS through and through that I can't believe anyone can possibly take it seriously.
Layer upon layer of meaning on every frame, every light/furniture/hairstyle/mask/etc to the point it becomes utterly meaningless.
And Cruise's sleepwalking acting here can't be faulted on him (he's just not like that in any other movie), so it clearly came from Kubrick's directing him that way (like George Lucas directing of Portman and Jackson in The Phantom Menace).
And lastly, secret societies (for adults at least) are NOT like that! I know several Rotary Club and Freemason members whom tell me they WISH their meetings were anything like this.
If you want orgies, you may find them at religious cults (like La Luz del Mundo in Mexico), politician's parties ("el Gober Precioso" from Puebla), or Ivy League fraternities or secret societies (on those ones I'm pretty sure wilder things take place).
